These pinions mesh with the l drivino Gears Q3 onthe traction wheels The Oears 19 and Q0 may be mounted on the shaft 21in any suitable manner, but, in the preferred construction, the largergear QG is connected to the shaft 21 by means of a compensating gearingQ which may be of any desired construction, and the gear 19 is rigidlysecured to one side of the gear 20, thus connecting the two gears to theshaft through the medium of a single compensating gearing. 1t will benoted that while the two pinions 14 and 15 may both be moved into theirinoperative positions, .e., out of mesh with th ir respective gears atone and the saine time, the arrangement of the grooved collars 17between the two pinions is such as to prevent both pinions meshing withtheir respective gears at the same time, thus rendering it impossible tothrow in both pinions, which would resnlt in breakage owing to thedifferent diameters of the pinions and gears and the fact that thepinions must rotate in unison with the driving shaft Q. The smaller ofthe pinions, 15, is of a diameter slightly less than the interiordiameter of the flange 9 forming a part of the friction member 6 and isadapted, when moved into its inoperative position, c., out of mesh withits gear 20, to enter the space within this flange, thereby enabling thefriction memlixer t3 to be placed close to the operative position of'the pinion and the gear 20, and adding materially to the compactness ofthe gearing as a whole.

An eccentric shaft Q6 is journaled in bearing brackets 2T, which aresupported by the main frame, and has rotatably mounted thereon a pinion28 adapted to mesh with the gear and preferably so mounted on saideccentric shaft as to be moved toward and away from the gear 2O when theeccentric shaft is rotated in its bearings. i friction drum 29 is alsojournaled on the eccentric shaft Q6 and is rigidly secured to, andpreferably fomed integral with, the pinion 2S, and, consequently rotatesin unison with that pinion. rEhe friction drum 29 is arranged inalinement with the friction member 6 and will be moved into and out ofoperative engagement with that friction member when the shaft 526 isrotated in its bearings. rEhe pinion 2S and friction drum Q9 are soarranged that the movement of the shaft in its bearings will carry bothmembers simultaneously toward their cooperating parts, but owing to thelength of the teeth of the pinion and its gear, these parts will beginto mesh before the friction drum comes into engagement with the frictionmember on the driving shaft, and, consequently, by the time the twofriction meinbers are in operative engagement, the pinion will be firmlymeshed with the gear and the movement of the shaft 2 and the frictionmember 6 will be transmitted to the gear 2O through the medium of thefriction drum 29 and pinion Q8. The movement of the pinion 2S relativeto the gear 20 is here shown as sufficient to entirely withdraw theteeth of the pinion from the teeth of the gear, but, obviously, this isnot an essential characteristic, it being necessary only that thecontact between the friction members be interrupted. it will be apparentthat the use of the intermediate gear 28 will cause the gear Q0 to berevolved in a reverse direction, thus driving the traction wheelsbackward and it will also be apparent that, owing to the fact that thepinion 28 will mesh with its gear before the friction members come intooperative engagement, the reversing mechanism may be moved intooperative position without interrupting the movement of the drive shaftand the friction member G carried thereby, it being only neeessary tomove the pinions 14 and 15 .into their inoperative gositions. rfheeccentric shaft QG has a crank arm 30, to which may be connected alsuitable operating handle or lever for rotating the shaft in its bearingand thereby controlling the reversing mechanism.

1t will be apparent that the construction and arrangement of the severalparts of the transmission and reversing mechanism is such as to renderthe mechanism as a whole very compact; and that it comprises a minimumnumber of parts. Further, it will be seen that the several moving partsof 'the gearing may be rendered inoperative by disconnecting the sleeve13 from the shaft and allowing the shaft to rotate freely therein, andthat the employment of the friction devices in connection with theintermediate reversing gear enables this gear to be moved into itsoperative position while the driving shaft is in motion without shock tothe machinery and the resulting liability of breaking` the same.

I wish it to be understood that I do not desire to be limited to thedetails of construction shown and described, for obvious modificationswill occur to a person skilled in the art.
